To all 'w hom itmai concern: I I Be it known that 1, GEORGE ROBISON MAV'IS, a citizen'of the United States, and

A a resident of Wymor'e, in the county of Gage and State of Nebraska, have invented a new and Improved Railway Cross-Tie, of which the following is a full, clear, and exact descri tion.

T s invention relates to a type of railroad cross ties that are formed of plate metal and concrete, and has for its object to provide novel details of construction for a cross tie of theeharacter indicated, which aiford a strong, shapely tie, Well-adapted for rail road tracks or street railway road bed construc't'ion- The invention consists innovel details and their combmationand arrangement, as isl1erelnaite1'fdescribed and defined 1n the 201 appended 'claims;

tubular core13, preferably formed of a piece of galvanized pipe having a suitable diameter and alength preferably equal with that of the shell 10, is inserted in the shell and bolts and other means which will be described. a

The track rails 14 shown to illustrate the cooperation of the improved ties for the pro- ;duction of'a railroad or street railway track, are of the T rail type, but said-track rails may be of a different form, such as are spe: cially adapted for street railway construction. The ends of the tie bar 12, arewidened track rails 14, the base flanges of the latter being seated on these ends of the tie bar.

structicn are imposed at one end of each, upon the pp osite flanges b, the remaining ends of thee amping plates being seated on the tie bar portions 12"., A reinforcing clamping bar 16, is introduced within the core 13, and preferably is convexed upon its a, are formedin the clamping plates, the tie bar 12, the upper wallof the shell 10, the core tube 13, and the clamping bar '16. Preferably the perforations in thetclainpin bar are threaded, and receive the threade track rails 14, at the same time drawingthe together, as is indicatedin Fig. 2.

, adjusted,.the diameter of the tube 13 peri its construction to such a form, as it will be Initting an insertion of a hand and rm. togetherwith a wrench for effecting such an adjustment. Centrally below each track rail 14, a truss late 17-is inserted within the shell l0, sai similar plates each having par- I allel top and bottom walls d, d, joined integrally to preferably curved side Walls (1 the top walls (1 at their centers merging into thimbles e, that encircle the core tube 13, as

shown in Figs. 3 and-4.

It will be noted in Fig. 2, that the walls (1 I prpiject as lateral ribs from the truss plate 17 alinement at the transverse centerthereofl greatly stiffen it, and it will be evident that the sup ort afforded by said truss plates will render t e cross tie very durable and ex ceedingly strong where this is essential,

adapting the tie to support the impact of heavy rolling 'stockthat may traverse the track rails,

In the top Wall of the shell 10, a plurality of perforations are 'formedat intervals in these perforations bein disposed opposite ter of the to so similar perforations in t e upper side of the core tube 13 and receive rivets 9, that when affixed therein coo erate with the boltf for holding the core tu e static any at the cenwall of the sh ll 10, which is very essentia for stability of the tube 13 and the convenient assembling of other details that have been described.

The body or shell is filled with a suit able mixture of concrete A, that will become rigid in a short time, and thus affords a tie body which c'o-acts with the shell and truss plates 17 to produce a strong, durable cross tie at a moderate costl In the construction of the road bed for a street railway track, the rails and cross ties are embedded in the ground so that the rails the sur are disposed substantially on a level with ace bf the road, consequently it will not be possible to place jam nuts on ends of the clamping bolts 15. To prevent the bolts from unscrewingit is preferred to employ a keeper plate 15, shown in Figs. 4 and 5, in connection with each clamping plate 15. he clamping lates 15 are all formed with ribs or flanges a ong their side edges as shown at i, to give them strength, and between these ribs on each plate 15, a keeper plate 15 is seated and held by a bolt 15, that passes through a perforation therein. clamping bolts 15 are screwed tight enough to properly bind the clampin ,plates 15 upon the base flanges of the tracli'rails, and the keeper plates 15 are likewise secured in place, an end portion m of each kee er late is bent so as to bear against the si e o the head of a corresponding bolt 15 and thus prevent the bolt from unscrewing.

ile it is preferred to give the body of the cross tie rectangular form, I 0 not confine When the as eiiicient and in some cases may be preferred, to have the base portion of the cross tie widened, and thus have more bearing surface where it is seated on the road bed.

The vmain portion of the bottom of the cross tie is of concrete, which is of advantage in that the contact of the concrete body with the ground will prevent creeping of. the tie in any direction, owing to its friction on the ground it rests upon:

The tie bar 12, not only prevents the spreading apart of therails .14, but also prevents wear onthe bolt of the tie, where the track rails seat thereon. It is feasible however, in some cases, to employ only the end portions 12, of the tie ar, whereon the track rails bear, and dispense with the intervening portion of the tie bar.

Having described my invention I claim as new, and desire to secure by Letters Patent:

1. A cross tie, comprising a four-sided metal shell, acore tube therein, and reinforgcing truss plates engaging the shell and tu e. 4
